To all whom t may concern;

Be it lrnoivn that l, FRANK Annina, a subject ot the Emperor of Austria, residing); at Chicago Ileights, in the eounty ot @ook and State of llllinois, have invented certain new and useful lmprcwenients in lliindoiv Construction, of which the following is a specification. y

My invention relates to VWindow construction and has for its ifnimary object the pro vision of an improved eonstruetion'ior Windou7 easements, Window-sash and the like, by means of which the glass is securely held `in position and by means ot which the re moval of a broken pane and the insertion ot' a new one are simple and rapid operations. A further object is the provision o1 a construction having the above features in combination With great strength.

Other objects and advantages of my invention will become apparent from the lolm lowing` description taken in conjunction with the accompanying drawings which illustrate the preferred embodiment of the invention and form a part of this speeiiieation.

1n the drawings- Figure 1 is an interior frontelevation of the upper portion ot a. Window easementl embodying the present invention;

Fig. 2 is a section taken onlino 2-2 oi. Fig. 1 and looking` in the direction indicated by the arrows; i

Fig. 3 is a. section taken on line 8 3 oit Fig. 1 and looking in `the direction indicated. by the arrows;

Fig. ,Je is an inverted view in perspective o1E a channelfshaped spring metal rib employed across the top of the easement;

Fig. 5 is a view in perspective of a similarly shaped rib employed on the sides oil the easement Fig. 6 is an interior front elevation of the ribs shown in Figs. 4l and 5, illustrating these ribs in their connected relation; and Figs. 7 and S are respectively a side elevation and a front end elevation of a spreader employed in attaching and removing the ribs of my invention.

Reference numeral 10 indicates a steel shape employed in forming the vertical sides of the easement iframe and 11 a steel shape preferably i shaped in eross-seetion Which I employ across the top and bottom oit' the easement. Each of the shapes 10 and 11 is provided with an exteriorly extending flange 12. Fach of the flanges 12 carries a plu.- rality oi3 undercut studs 13 jnojecting .inwardly o1 the easement and all placed in a common vertical plane` spaced suilie-iently from the base 10 and 11 ot the shapes to accommodate a pane of glass 1-i and a body of putty 15 on eaeh side of the glass. it 1G is indicated a spring' metal channel-shaped rib, substantially lll-shaped .in cross-section, and int-urned along the extremity.' of its side Webs as at 17; this riby being` the one employed at the top and bottom of the casement. Reference numeral 18 indicates a channel-shaped spring' metal rib employed in the sides oi the window easei'nent and which is aduplicate o12 the rib 1G as tar as the cross-section is concerned. lilach ol the ribs 1G and 18 is slotted as at 19 substair tially opposite one ot the studs 13 and is preferably slightly notched at its center, as at 21, to aeeonnnodate the shank 22 ot a spreader 23, thespreader being inserted into the transverse web of either rib and turned within the rib, as shown in dotted lines in Fig. 3 in order to expand the tree edges of the side Webs of the rib suilieiently to permit the inturned portions 17 to pass over the cross diameter of the projecting studs 13. y

1n fitting together the ribs 1G` and 18 the ends ot the rib 1G at top and bottom et the `easement are split and a tongud 22 downbent to lit within the open ends ot the ribs 1S, as indicated in F 6. in order that the ribs 1S may be removed ii'om the casement without distortion the inbent portions 17 of the tree edges of the side Webs of the ribs 18 are cut away, as at 23 'in Figs. 5 and G, at the upper and lower ends ot both side ribs.

In assembling a Window in the easement of the present invention, the studs 13 being in place in the flanges 12, the operator inserts the header 23 in each slot 19 and by turningl the header Within the rib spreads the portions 17 apart suilieiently to permit the side Webs of each rib to snap over and bind beneath the undercut head ot each stud 13, as best shown in Figs. 2 and 3. 1n this operation the upper and lower ribs 16 are first set in place, following,1 which the side ribs 18 are positioned. 1f desired, the glass 14 and a portion of the body ot' putty 15 may be positioned in the shapes 10 and 11 before the ribs 16 and 18 are set, and following the setting of the ribs that portion of the body of putty standing between the glass and the ribs may be worked into place by means of a putty knife in the ordinary manner. In removing broken glass from the easement the broken portions of glass and the dried putty about their edges are scraped from the recess formed between the shapes 10 and 11 and the ribs 1G and 18, following which by use of the spreader 23, the ribs are readily removed from studs 18. A portion of the putty bodyl and the new glass are positioned in the shapes 1 0 and 11, following which the ribs are set and the remainder ,of the putty worked in, as above described.

It will be seen that owing to the spring character of the metal composing the ribs, these ribs are securely held upon the studs 13, and the glazing of the window is rendered a'n extremely rapid and easy operation because of the readiness with which the ribs may be attached and removed. Preferably the tongues 22a are of suiiicient width to lit snugly within the ribs 18, whereby it will be seen that the true alinement will always be maintained with ribs 16 and 18, regardless of any slight distortion in the manufacture of either of these ribs.

While I have illustrated the preferred embodiment of my invention, it will be obvious that one skilled in the art may make modifications thereof without departing from the spirit of the invention. I wish, therefore, not to be restricted to the precise embodiment shown except in so far as the same is limited in the appended claims.

I claim:

1. In a Window casing, the combination with undercut studs, of glass-holding ribs adapted to snap over said studs, each of said ribs comprising a spring metal channel having the free edges of its side webs bent toward each other, said channels having their bottom webs slotted at a point opposite each of the studs for insertion of a tool.

2. In a window casing; the combination with a frame; of an upper glass-holding rib comprising a channel member split at its ends, and a tongue bent outwardly of said channel at the split portion of each end; and channel-shaped side ribs each abutting at its upper end against the bottom surface of said upper rib; each of said tongues litting snugly between the side webs of its respective side rib.

3. In a window casing; the combination with a frame; of undercut studs projecting inwardly thereof; upper and lower glass holding ribs comprising metal channels having out-turned, resilient side webs the free edges of which are inbent for engagement with the studs; side ribs abutting at their ends against the opposed inner surfaces of said upper and lower ribs and similar in cross-section to said upper and lower ribs; and a tongue formed at each end of each upper and lower rib and projecting into and closely fitting the channel of each side rib.

4. In a window casing; the combination with a frame; of undercut studs projecting inwardly thereof; upper and lower glassholding ribs comprising metal channels having out-turned, resilient side webs the free edges of which are inbent for engagement with the studs; side ribs abutting at their ends against the opposed inner surfaces of said upper and lower ribs and similar in cross-section to said upper and lower ribs; and a tongue formed at each end of each upper and lower rib and projecting into and closely fitting the channel of each side rib; the inbent portion of lthe free edge of each side web of the side ribs being cut away opposite each of said upper and lower rib tongues.

In testimony whereof I aiix my signature.

FRANK ARBTER.
